Got em all tore down now, just gotta get some chem dip to soak em in now.

 

Ok, got the head pulled off. You guys think it is salvageable? Cant get it to turn though. Any ideas?

 

Yes, it might be salvageable.
Do NOT turn the engine over. The last thing you need is grinding the rust and junk into the cylinder walls.

You'll need to split the engine case and take out the crank and pistons out from the bottom.
Then you could try cleaning up the walls with a hone.
But most likely, you will still have pitting in the cylinder walls - so it won't seal and build proper compression.
Hard to tell from the pics, but the walls look more than just a touch of surface rust. Looks chunky.
If you really like doing engine work, the correct way & costly way would be have a shop bore the cylinders slightly over.
Then rebuild the engine with oversized piston. You'd essentially have a brand new engine then.

The cheaper & quicker way to go, would be to just fine a good used engine.
Depends on what your goals are for this bike.

 

Thanks man, just picked up a complete f3 engine on frame. So I have looked though a few threads on the topic. My question is, since I will be using the carbs that came with the f3, I need to transplant the harness as well for tps. Would it be possible to just use the f2 harness and move over the f3 cdi and run new wires for the tps?
